Causes of Autism

What Are The Causes Of Autism?

There is no known single cause of Autism. Many causes of Autism have been investigated and our understanding is still incomplete.

Research indicates that genetic factors predominate but it is unclear which genes may be responsible. It is generally agreed, however, that Autism is likely to have multiple causes, including some pre-natal factors that result in the common symptoms of Autism.

Autism also tends to occur more frequently than expected among individuals who have particular medical conditions including fragile X syndrome, tuberous sclerosis, congenital rubella syndrome and untreated phenylketonuria (PKU).
